Answer key
- 1. It significantly diverts attention, slowing reaction time — Handling a phone diverts both mental and physical attention from driving, dramatically increasing stopping distances and reaction times.
- 2. No, they exceed both the 36kg and 150cm thresholds so a standard seat belt is sufficient — Children who exceed both 150cm in height and 36kg in weight may use a standard adult seat belt without a child restraint.
- 3. Only if the front passenger airbag has been deactivated — A rear-facing child seat may be used on the front passenger seat only if the airbag has been deactivated. An active airbag could cause fatal injury to the child in a collision.
- 4. Pull off the road safely, rest and take a break before continuing — The only effective remedy for driver fatigue is rest. You should pull over safely, take a break or short sleep before continuing your journey.
- 5. 12 points — A fully licensed driver who accumulates 12 penalty points within a 3-year period is automatically disqualified from driving.
- 6. 2 more points — Novice drivers are disqualified at 7 penalty points. With 5 already recorded, just 2 more will trigger disqualification.
- 7. Yes, Gardaí have the power to stop any vehicle — Gardaí have the legal power to stop any vehicle at any time and request the driver to produce relevant documents.
- 8. Driving licence, insurance certificate, and NCT certificate (if applicable) — A Garda can require you to produce your driving licence, evidence of motor insurance, and a valid NCT certificate if the vehicle is subject to testing.
- 9. When the tyres are cold, before a long journey — Tyre pressure should be checked when the tyres are cold because driving heats the air inside, giving a falsely high reading.
- 10. Must not be used and should be replaced immediately — A bulge or cut in a tyre sidewall indicates structural damage that could cause a sudden blowout; the tyre must be replaced.
- 11. Whenever visibility is seriously reduced due to poor weather — Dipped headlights must be used any time visibility is poor, such as in heavy rain, fog, or snow, even during daylight hours.
- 12. Only in fog or falling snow when visibility is seriously reduced — Rear fog lights are very bright and can mask your brake lights; they should only be switched on when visibility is seriously reduced.
- 13. The vehicle pulls to one side when braking — Pulling to one side during braking usually indicates uneven brake wear or a fault such as a seized calliper, which requires immediate inspection.
- 14. Apply firm, continuous pressure to the brake pedal and steer around the obstacle if necessary — With ABS you should press the brake pedal firmly and hold it; the system modulates braking automatically, and you can continue steering to avoid the hazard.
- 15. The vehicle wanders or drifts without the driver making steering inputs — Wandering or pulling to one side when the steering wheel is released can indicate worn steering or suspension components and should be inspected.
- 16. Worn or loose suspension joints such as ball joints or anti-roll bar links — Knocking from the suspension area often points to worn ball joints, anti-roll bar bushes, or other linkage components that need replacement.
- 17. A crack or chip within the driver's critical vision area — Cracks or chips in the driver's forward vision zone are an NCT failure item because they distort or restrict the driver's view of the road.
- 18. Normal condensation that clears once the engine warms up — Condensation in the exhaust system produces harmless white steam when starting a cold engine; it disappears once the engine warms up.
- 19. To assess whether a vehicle meets minimum roadworthiness and safety standards — The NCT examines key safety and emissions items to ensure vehicles on Irish roads meet the required standard for safe operation.
- 20. Yellow diamond with a black symbol — Irish warning signs are yellow diamonds with black symbols. This distinguishes them from the red triangles used in most of continental Europe.
- 21. Octagon — The STOP sign is an octagon (eight sides) with a red background and white text. Its unique shape allows drivers to recognise it even when partially obscured.
- 22. Maximum speed limit of 50 km/h — A circular sign with a red border and a number is a maximum speed limit sign. Drivers must not exceed that speed.
- 23. Roundabout ahead — A yellow diamond with a circular arrow warns that a roundabout is ahead. Drivers should prepare to give way to traffic already on the roundabout.
- 24. No vehicle may cross or straddle the lines under any circumstances — Double continuous white lines create an absolute prohibition on crossing. No vehicle may cross or straddle them regardless of conditions.
- 25. When turning right and waiting for a gap in oncoming traffic, provided your exit lane is clear — The only permitted exception is when turning right: you may wait in the box for a gap in oncoming traffic, as long as your exit road is not blocked.
- 26. No, parking on zig-zag lines is prohibited at all times — Parking or stopping on zig-zag lines is prohibited at all times; they exist to keep the crossing clear and maintain sightlines for pedestrians and drivers.
- 27. Red changes directly to green, with no combined red-and-amber phase — Ireland does not use the combined red-and-amber phase before green; the sequence goes directly from red to green, unlike some other European countries.
- 28. 45 minutes — Candidates are given 45 minutes to answer 40 questions. The test is taken on a computer touchscreen at an RSA test centre.
- 29. L plates (white with red L) — A learner permit holder must display L plates (white background with a red L) on both the front and rear of the vehicle at all times while driving.
- 30. 20 mg per 100 ml of blood — Learner permit holders have a lower blood alcohol limit of 20 mg per 100 ml of blood, compared to 50 mg for experienced drivers.
- 31. 2 years — N plates must be displayed for the first 2 years after passing the driving test and receiving a full licence for the first time.
- 32. 100 km/h — The default speed limit on national roads (N-roads) that are not motorways is 100 km/h.
- 33. A school or residential area where a lower limit has been set — Special speed limits of 30 km/h are commonly applied around schools, playgrounds, and residential streets where vulnerable road users are present.
- 34. Red letter L on a white background — Learner drivers in Ireland must display red L-plates (red letter L on a white background) at the front and rear of the vehicle.
- 35. Traffic already circulating on the roundabout — At all roundabouts in Ireland, vehicles already on the roundabout have priority. Approaching drivers must yield to circulating traffic.
- 36. Give way to the traffic on the major road before entering — A Yield sign requires you to slow down and give way to all traffic on the major road before entering. You may only proceed when it is safe to do so.
- 37. For access to a premises or in an emergency, never to overtake — A continuous (unbroken) white centre line must never be crossed for overtaking. You may only cross it for access to a premises or side road, or in an emergency.
- 38. At a pedestrian crossing — Overtaking is prohibited at pedestrian crossings. A broken white line, a clear dual carriageway, and the left lane of a motorway are all places where overtaking is permitted when it is safe to do so.
- 39. In the event of a breakdown or emergency stop — The hard shoulder is reserved for genuine breakdowns and emergencies. Driving on it or using it to pass other traffic is illegal except in an emergency.
- 40. At least four seconds to allow for increased stopping distances — In wet conditions, braking distances increase significantly. You should at least double the dry-weather two-second rule, giving a minimum of four seconds in rain.
